The IUPAC notation for this reaction is AxhHDN. In dealing with alcohols, phosphorus oxychloride in a pyridine solvent can be used to carry out this reaction. The presence of poor leaving groups increases the favorability of (*) Hoffman products in this reaction.  It is aided by an anti-periplanar configuration, and in the case of alkyl halides it is promoted by strong base. This second order mechanism is favored by secondary and tertiary alkyl halides, and its product is governed by Zaitsev's rule. Unlike its primary counterpart, this reaction does not have a carbocation intermediate, but it does result in an alkene. For 10 points, name this one step bimolecular elimination reaction.
